IIWPROVEMNTIN MANUFACTURE OIE CHAINS.

The Schedule referred to in these Lettera Patent and making part of the same.

of Cleveland, in Cuyahoga county, and State of Ohio,

have invented new and useful Improvements in Machinery for Making Ohaing' and I do hereby declare v that the following is a full and exact de icription thereof,

reference being had to-the accompanying drawings, and to the letters of reference marked thereon.

Figure l is a side view ofthe machine in operation.

Figure 2 is a View looking down on to the machine.

Figure 3 isa sectional view.

Figures 4 and 5 are views of what we call turninguon.

In constructing, I make, of cast-iron, the form represented at A, figs. l and 2, having a slot for foot-lever l j, and a projection below for the fnlcrum-pin g and the projection fl, the die to form the chain around, and a notch at n, iig. 3.

I drill a hole for pin at p, figs. I and 2, to turn the hooks on. I fasten it on to a table, as shown in tig. 1, with the foot-lever hanging down, with a pin at f, for the foot to rest on, and a seat, S, to sit on while operating the machine.

I fasten the hand-levers H H with `bolt b b, iig. 2. I take pieces of wire of the right length, and place them in the hooks of the last link, and across the machine, as shown by the red lines at \V.

I then push on thev foot-lever, which is shaped according to the shape of the cross-bar, and next pull the levers H H, and bring the Wire around the die d, as shown in iig. 2, c c.

I next take the turning-iron, iigs. 4 and 5, and place it as shown in fig. 3, the hooks z z under the ridge n, and the shoulders x x on the wire, and press' it down as shown in said fig. 3.

I then put the pin p, iig. 2, through the die, as shown, and put the turning-iron under the wire, as shown at o, iig. 1, and turn it up, as shown at o k, same ligure, and that bends the end of the wire around the pin p, which finishes the link. 4

The pin p should be made of steel. The foot-lever has a notch, to hook on to the link c, to prevent its rising at that end while it is being bent down at a, as shown in iig. 3, for making wide links.

For making wide links, for ladders, 8m., we' use two levers, fl, one near each back corner of the die, and the two front corners of die d project over the form A, and turn one hook at a time.

I claim as new, and of my inventionl. The combination of the form A, d ie d, and hooked lever l f, constructed and arranged substantially as described.

2. 'Ihe combination of the turning-iron, iig. 4, with the form A and die (I, substantially as described.

3. The combination, substantially as herein described, of the form A, die d, and levers H H and l f. 4. In combination with the devices set forth in the first clause of claim, the seat S, arranged substantially as described.
